Treo users are known as being loyal, but the fact that Palm hasn’t update the device’s look — short of killing the antenna — in quite awhile has left them hungry, especially since the Centro line of tiny smartphones has been so successful.

The perfectly blurry spy shot shows the Sprint logo, which is in line with what we’ve heard about Sprint being the first to carry the handset. we havent’ gotten official word from our Palm rep yet of the date and badge, but it all seems likely.
